Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 319.42 g/mol gives Monoundecyl Phthalate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Monoundecyl Phthalate (CAS 51622-03-8), molecular formula C19H27O4 and molecular weight 319.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Monoundecyl Phthalate (C19H27O4) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Monoundecyl Phthalate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
